Pregnancy test – positive and negative


Pregnancy test – positive and negative

Home pregnancy test is based on the same principle as the test in a medical facility. Only in the hospital or laboratory is necessary to hand over blood from a vein for determination of HCG and test from the pharmacy it’s much easier: you only need to hold the test strip under the urine stream or dipping it into urine (preferably morning) for a few seconds. If in urine there is the pregnancy hormone, then the test will appear two bars, if not then only one.

Modern pregnancy tests are effective from the first day of menstruation (or 14 days from conception). Some manufacturers write that their test can diagnose pregnancy after 7-8 days from the moment of conception, however, relying on this is not: by this time, the HCG hormone can either not produce or produce in such small amounts that the test did not identify.

It’s safest to use the test on the first day of delayed menstruation. To be sure, you can repeat the procedure several times. When you confirm a positive result with a very high probability that you are pregnant.

What can affect the result?
The result may be a false positive in that case, if you are being treated for infertility and taking specific drugs containing HCG (pregnyl, profasi, choragon, etc.). If you do a pregnancy test shortly after taking the drug, it may fix a missing pregnancy.

Also elevated levels of HCG after abortion persist for some time (about a week) and if you during this period will hold the test, you will see two strips. This is normal and does not mean that the abortion was unsuccessful. Just the body for some time will produce an increased amount of this hormone.

In addition, the tests may give an incorrect result if:

  • the woman did not follow the instructions;
  • the test is carried out too early;
  • at occurrence of hormone-dependent tumors;
  • when ovarian dysfunction;
  • in the pathology of pregnancy.

If it is suspected that at a certain moment of conception was, from this time only after 28-35 days can do a pregnancy test. Also it can be done approximately 10-14 days after the first day of delayed menstruation. Earlier this test is not recommended, as in this case, the result may be incorrect.

A pregnancy test at home can show the presence or absence of pregnancy. Almost all tests when displaying two stripes indicate that the woman is pregnant. If the second strip was manifested clearly, we need a couple of days to repeat the procedure to confirm the correctness of the information received. Poor visibility the second dash makes it clear that the test was incorrect.

In normal and ectopic pregnancy test gives the same positive answer. Therefore, to eliminate the attachment of a fertilized egg outside the uterine cavity that may be hazardous to women’s health, one should immediately consult a physician.

The main advantage of home tests is that they can be bought in any pharmacy and can I study in relaxed and comfortable surroundings.

How to use a pregnancy test

How to use a pregnancy testThere are several types of pregnancy tests, the instructions to every detail how to do the test correctly.

Strip test (test strip)

The easiest, cheapest and most common test. The test strip should be lowered to a certain point in a container with a morning urine for 10-20 seconds. After the test is placed on a horizontal surface. After a few minutes you can watch, what is the result of the test. One strip – you’re not pregnant, two stripes – the pregnancy.

Tablet test

Arranged in a similar way. Only a paper strip is placed in a plastic housing. Pre-assembled morning urine is dropped in the hole supplied with the test pipette and watch the result. About it will tell one or two stripes on the pregnancy test.

Test Jet

More convenient of the two previous ones, because the urine will not need to raise test enough to place it under running. Urine is not necessarily morning, as jet a pregnancy test is usually more sensitive. Positive pregnancy test – two strips, and if there was only one bar, so, no pregnancy.

Digital test

In these tests, there is a special strip – receptacle, which can optionally be lowered into the container from the urine stream or substituted. A pregnancy test shows the result after 3 minutes. When the test came “+” or the words “pregnant” – you have a positive pregnancy test, if “–” or “not pregnant” – that is negative.

Online pregnancy test

Now the Internet can find advertisements of free pregnancy tests online. In the best case is just a hoax. At worst – a way to make fraud (when, for example, to pass the test you must first send an SMS to a specific number). Such online pregnancy tests are alike in one thing – you will get the result after a few minutes, without any special effort. Another thing is whether they are reliable.

Judge for yourself, the number of such rapid tests for pregnancy, for example, offer to put a finger to the blue squares on the screen and if in a few minutes he will be red – you are pregnant))). However, even if you will not put a finger on the screen, the small box after some time turns red. Other tests before reaching a verdict, offer to answer a number of questions. For example, “have you had a recent unprotected sexual intercourse?” and “do you Feel breast tenderness and nausea in the morning?”. It’s kind of an interactive pregnancy test, answering the questions which you will learn, what is the probability of conception. How useful is this test for determining pregnancy – you decide, but any doctor you absolutely not advise it to anyone.
